A colon resection (also known as a colectomy) is an inpatient procedure in which the cancerous portion of the colon is removed. To ensure all of the cancerous tissue is removed, a small portion of healthy colon tissue adjacent to the cancerous tissue may also be removed. On average, one-fourth to one-third of the colon may be removed during a colectomy. The remaining portions of the colon are then connected.
